Here is Jan's new panorama in circular form. We are right beside the little crater Orion. The even smaller crater (pit) Mariner 4 is just to the SW of the rover.

... and a circular version of it. Thanks! That small crater just north of us is visible in HiRISE. (EDIT - it's called Casper. Orion and Casper were the Apollo 16 LM and CSM respectively.) One more drive and we'll be on the rim. Maybe two drives to allow for some careful positioning right on the edge.

Think we really need to visit that slab. it could be exposed Carbon ice.Gypsum..or whatever.. it seems rigid in place and not eroding on par with the crater and it seems linked on the Hirise Image to an interesting surface feature that may even be related to the gully
Its brightness is very noticeable.   What do you guys think? I can't recall seeing a feature like this on that scale |

QUOTE (jvandriel @ May 5 2017, 10:49 AM)  and the Navcam L0 view on Sol 4720. Jan van Driel Thank you very much Jan van Driel  Can those ripples in front of the rover be considered as "sand traps" ? |

"I can't recall seeing a feature like this on that scale"
Look back 1000 sols to the images on this page: http://www.midnightplanets.com/web/MERB/sol/03749.html (Wdowiak Ridge, sol 3749) The geologists who run the mission have not noted this as anything especially unusual. I personally think it's just the same as lots of other lumps and bumps seen along the crater rim. There are much more compelling reasons to go down into the crater again, where broad areas of outcrop downhill from the 'gully' will be explored later. -------------------- ... because the Solar System ain't gonna map itself.

This is Jan's half-panorama from sol 4720 in a circular projection. It makes the slopes look much steeper than they really are. I would anticipate a drive out onto that spur just to the north of us (top of the image) to get a better look across the slope and into the valley.

QUOTE (Steve5304 @ May 5 2017, 03:01 PM) Think we really need to visit that slab. it could be exposed Carbon ice.Gypsum..or whatever... Its brightness is very noticeable. From the latest PS report: QUOTE It was intriguing enough for the scientists to consider dispatching Opportunity for a quick visit. It would be their only chance since once the rover descends into Perseverance Valley, she won’t be coming back this way again. “Our estimate was that it would take a month to go to Winnemucca, look at it, kick around, and get back,” said Golombek. Ultimately, the decision was – no go And ice would be much brighter than this - remember that Mars soil is usually very dark. Check out some of those old Phoenix ice pics. |
